4-1. Maintenance and care
CAUTION
■Cleaning detergents
●Do not use organic substances such as benzene or gasoline, acidic or
alkaline solutions, dye, bleach or other detergent. Doing so may discolor
the vehicle interior or cause streaks or damage to painted surfaces.
●Do not use polish wax or polish cleaner. The instrument panel's or other
interior part’s painted surface may be damaged.
●Do not use a chemical agent containing silicone (highly-polymerized sili-
con compound) when cleaning any of the electrical appliances such as the
air conditioning, all switches and their surrounding areas.
If silicon (highly-polymerized silicon compound) contacts these compo-
nents, it may cause the electrical appliances to malfunction.
■Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of
leather surfaces.
●Remove any dust, dirt, sand, oil spots etc. on leather surfaces immedi-
ately.
●Do not expose the vehicle to direct sunlight for extended periods of time.
Park the vehicle in the shade, especially during summer.
●Do not place items made of vinyl, plastic, or that contain wax on the uphol-
stery, as they may stick to the leather surface if the vehicle interior heats
up significantly.
■Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes
into contact with electrical components under the floor of the vehicle, and
may also cause the body to rust.

Maintenance and care
WARNING
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
■When working in the engine compartment
●Keep hands, clothing, and tools away from the moving fan and engine
drive belt.
●Be careful not to touch the engine, radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper or rags, in the
engine compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
●Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
■When working near the electric cooling fans or radiator grille
Vehicles without a keyless access with push button start system: Be sure the
engine switch is off. With the engine switch in the “ON” position, the electric
cooling fans may automatically start to run if the air conditioning is on and/or
the coolant temperature is high. ( →P. 304)
Vehicles with a keyless access with push button start system: Be sure the
push-button ignition switch is off. With the push-button ignition switch in
“ON” mode, the electric cooling fans may automatically start to run if the air
conditioning is on and/or the coolant temperature is high. ( →P. 304)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.
CAUTION
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air. Also a backfire could cause a fire in the engine compart-ment.
